Subject: pan/midgard; Dump successor graph when printing MIR
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a08e9511e34e87b445475249df329f9c3e4c4e99;p=mesa.git

pan/midgard; Dump successor graph when printing MIR

We just use the pointers of the midgard_block*, which is crude, but it
gets the point across and will help debug successor related issues.
